What the guy showed me was a box on my firewall that he says is bad.
I went to have it smog tested and it ran high hydro carbons at idle idle was 690-710 and it passed everything else/
My question is this the problem or can I test this first. I am not a part changer but a problem solver..Any input would be appreciated.
Thank you.

34 - EVP voltage above closed limit.

Looks like you have a bad EGR valve position sensor.

It most likely is the sensor. The tech probably checked your EGR {I guess I shouldn't assume anything these days} valve by either a vacuum test or by manipulating the rod underneath the diaphram if possible.

If you want to take a shot at something, you could take the EGR off and clean the plunger with carb cleaner. Hopefully the gasket will survive the R&R.
